Service invocation

• Invoke other services in your cluster or environment
• Create a gRPC enabled app, and invoke Dapr over gRPC

Middleware

• Authorization with oAuth

State Management

• Setup Dapr state store
• Create a service that performs stateful CRUD operations
• Query the underlying state store
• Create a stateful, replicated service with different consistency/concurrency levels
• Control your app's throttling using rate limiting features
• Configuring Redis for state management

Pub/Sub

• Setup Dapr Pub/Sub
• Use Pub/Sub to publish messages to a given topic
• Use Pub/Sub to consume events from a topic
• Configuring Redis for pub/sub

Bindings and Triggers

• Implementing a new binding
• Trigger a service from different resources with input bindings
• Invoke different resources using output bindings

Actors

For Actors How Tos see the SDK documentation

• .NET Actors
• Java Actors

Observerability

Metric and logs

• Set up Azure monitor to search logs and collect metrics for Dapr
• Set up Fleuntd, Elastic search, and Kibana in Kubernetes
• Set up Prometheus and Grafana for metrics

Distributed Tracing

• Diagnose your services with distributed tracing

Security

Mutual Transport Layer Security (mTLS)

• Setup and configure mutual TLS between Dapr instances

Secrets

• Configure component secrets using Dapr secret stores
• Using the Secrets API to get application secrets

Components

• Limit components for one or more applications using scopes

Developer tooling

Using Visual Studio Code

• Using Remote Containers for application development

• Developing and debugging Dapr applications

• Setup development environment for Dapr runtime development

Using IntelliJ

• Developing and debugging with daprd

SDKs

• Serialization in Dapr's SDKs

Infrastructure integration
